• Host connection failure: VMs, warehouses of data inaccessible (in gray)

  Hello everyone,

  I have 1 ESXi host 5.1 throwing alarm: host connection failure. Al a SNMP trap for the entity has been sent.

  I have 10 servers ESXi 5.1 all the amanged by 1 5.1 VCenter server.

  8 ESXi servers belong to a cluster HA and 2 are not in a cluster.

  The issue I'm facing is with 1 ESXi host that is outside the cluster.

  The virtual machines on that host are powered OFF. I am not able to turn on. I am not able to Vmotion them. However, if I remove them from the inventory and add them to the inventory on a different host running, VM works very well.

  Shared on this host data warehouses show Greyed out as well except the local data store (VMFS). I have 1 VM on the local disk of this host and I can power ON the property. But all other virtual machines are the shared data store (NFS - Netapp) and I can not turn on this particular host 1.

  Same data warehouses (NFS - Netapp) are shared with the other 9 (Clustered and nonclustered hosts) ESXi hosts and data store is fine and detected by all hosts.

  I tried to reboot the host several times but without success.

  Can someone please share their expert advise on how to fix this?

  Please see the attachment for details of esxi host does not.

  Thank you

  AG.

• Windows 7 professional - connection failure: unknown username or bad password.

  I have new xps computers 8700 identical Dell running windows 7 Professional.  The new dells replace the old dell dimension computers Windows XP Edition Professional.  I traced a drive 'f:' of network easily to my server from windows 2000 of the first Windows 7 Professional machine.  But when I tried to map the "f:" network drive on my windows 2000 Professional 2nd new windows machine Server 7 I got the following message: "connection failure: unknown username or bad password."  The computers are identical.  After the introduction of the first professional machine of windows 7 with success and mapping the drive "f:" on my server, I cloned the drive hard so that all my apps and settings would be the same on the second Professional machine of windows 7.   I tried to change the 2nd windows 7 professional name of the computer, but I still regularly get the "connection failure: unknown username or bad password."  Any ideas or suggestions would be greatly appreciated.

  Thanks in advance,

• Differences between the ISCSI connections to the storage in vSphere 4.1 and 5.0.

  I'm in trouble of setting up the connections of storage in a new VSphere 5.0 test environment. In our environment VSphere 4.1, it was possible to create a virtual switch add two Broadcom NetXtreme II 5709 NIC. Set assets. IP Hash value as load balancing. (LACP Etherchannel on physical switches) This configuration uses a grain port and a single IP address. Then add our NetApp NFS storage and ISCSI Equillogic storage. In VSphere 5.0, I can't create this same configuration. I have to create separate with separate IP addresses vmkernal ports? The idea was to have redundant connections to the storage and flow of these two NETWORK cards. Possibly adding additional if necessary to the futuer NETWORK cards. Any help with this would be greatly appreciated.

  How can I work around this:

  "VMkernel network adapter must have an active link exactly and no waiting rising to be eligible for the iSCSI HBA connection."

  I can certainly say that the way which allows you to configure the iSCSI Multipathing is incorrect.

  The main idea is to let Native Multipathing Plugin to decide what network path to choose, not the vSwitch.

  At the level of the network layer, you must have 1 VMK by a physical NIC.

  This technique applies as well for vSphere 4.1 and 5.0, but with the 5.0 it is configured easier and more quickly.

  Here's a very brief consequence of steps

  1. get 2 VMK interfaces and assign an IP by each VMK.

  2. set each VMK to use only one physical NETWORK adapter

  3 GB with storage iSCSI software adapter, turn it on and bind your VMKs 2.

  4 connect to your iSCSI storage space

  5 rescan devices, create the VMFS datastore

  6. set the desired load balancing VMFS method or just set up a prior default create new VMFS

  and it is strongly recommended to read this guide - http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-50-storage-guide.pdf

• ESXi 4.1 VMs down every Monday morning

  Greetings,

  He started last week; Saturday around midnight my host closed ESXi my two VMs I had to manually start this Monday morning. I don't know where this problem start. My store of data on my host computer has 4 GB of free space; could this be the cause?

  Thank you for your time and effort

  Fred

  With the help of converter to reduce the size of the drive will certainly help. You will need to decide if the amount of recovered space is sufficient to respond to the needs of your short term.

• iSCSI connection

  Can someone give me an idea about the best way to configure my connection iSCSI in vMware?

  I'm under ESXi 4.1. I have three ESX host. On each host, I have two other network connections to the outside for each host. It is advisable to configure a vmkernal port, assign an IP address and use a one as the main network connection and the other as secondary or load balancing, both.

  Or and im not having a chance at this moment doing this... install a second port of vmkernal using a separate virtual switch, assign it a second ip address and having only one main connection on for each virtual switch. Give me two connections to my iSCSI SAN for each host.

  Thank you

  Wayne

  Hi Wayne,

  The best way is to have a unique vSwitch with two other cards attached physical. Then, create two VMkernel ports for iSCSI connections. Take a look at the next section for a full description of this type of configuration.

  It will be useful.

• Cannot Connect to Host ESXi 4.1 with browser or Client VI

  Hi, I have a strange problem which has persisted since I first installed ESXi 4.1 on a server. First my setup:

  • ESXi Installable on a HP DL380 G6 server, 32 GB of RAM, 4xEmbedded NETWORK ports, Port NIC, 2 iSCSI x QLogic QLE4060C HBAs 1xDual adapter

  • HBAs configured for Jumbo and static IP frames but except that all the settings are default

  We have installed ESXi 4.1 with only the built-in port #1 connected to the switch. Everything went well and we were allocated the only active NIC (vmnic0) as the management interface. Once installation is complete, we were able to connect to the management interface using a browser and the VI client.

  We then connected NETWORK card and remaining HBA ports to the switch without loss of connectivity to the management interface. During our next restart we could no longer connect directly to the host using a browser or the VI client but could still ping the IP.

  We tried to restart the management agents, but it did not help.

  Here are the different startup scenarios, we tested and the results:

  Scenario #1 - Boot with built-in NICs, DP adapter cards, network and HBAs connected to the switch.

  • Can we ping the IP of host of Mgmt? = Yes

  Can • we consult to the IP host of Mgmt or connect using the VI Client? = NO

  Even if we try to unplug the adapter DP and HBA ports after starting we still cannot connect to the management using the Explorer or the VI Client interface. A reboot is required, and the script #2 or #3 must be followed.

  Scenario #2 - start with only the embedded and DP adapter NIC connected to the switch.

  • Can we ping the IP of host of Mgmt? = Yes

  Can • we consult to the IP host of Mgmt or connect using the VI Client? = NO

  If disconnect us the two ports of adapter DP we can then connect to the host via the browser or the VI client without having to restart. We can reconnect them and we continue to have access to the host, and everything is fine.

  Scenario n ° 3 -Boot with only the NIC integrated, including the Mgmt NIC connected to the switch.

  • Can we ping the IP of host of Mgmt? = Yes

  Can • we consult to the IP host of Mgmt or connect using the VI Client? = Yes

  Then we connected the DP adapter and the adapter port HBAS to the switch and all the connectivity was very good. This scenario is our solution for now.

  Other information

  The QLE6xxx ESXi module takes about 5 minutes to load during startup, when the HBAs are connected to the switch, but it loads successfully. Not sure if this is normal or not.

  Thank you in advance for your help!

  This looks like a very unusual network for me configuration.

  Could you post a screenshot of virtual network configuration and add a few comments on the different configuration of the vSwitches and uplink connected.

  If I understand correctly that you have at least 3 vSwitches (management, virtual machines, and iSCSI), however, from what you wrote so far I do not completely understand how implement you.

• If I put in place an openfiler VM as a data store iSCSI & vmfs on two ESXi hosts, both ESXi hosts can access two data warehouses?

  If I put in place an openfiler VM as a data store iSCSI & vmfs on two ESXi hosts, both ESXi hosts can access two data warehouses?

  The reason why I ask, is that I have two hosts ESXi ESXi 4 running.  I do my backups with ghettoVCB, which I modified to create thin backups on one of the drives the.  I then wput them to the server, which causes them to become thick.  Directly targets the backup in a vmfs iSCSI on the server in the face shop.  It would save a step and the vmdk backup should remain thin.

  Thank you!

  The short answer is Yes. If you allow the ESX servers to see the LUN. This setting is configured to the Openfiler.

• Connection failure: unknown username or bad password

  I use Thunderbird without problem for businesses for nearly eight years. I currently run at the top of a tower with Windows 7 Pro. There is only a single account/e-mail address on Thunderbird.

  This morning when I went to check my e-mail I have my password is requested, then received the error 'sending of password did not. Mail server exchange.company.com replied: connection failure: unknown username or bad password. "I retried the password, restart Thunderbird and tried again, but still not received the same error. I sent an email from Thunderbird test which was very good. I am also able to connect to the server via web browser and I am able to send and receive emails on my mobile device.

  I erased all the saved passwords of Thunderbird and I checked account settings, but I am still unable to download any email Thunderbird.

  Apart from the deletion of the account, I don't really know what to do here. Any help would be appreciated! Thank you.

  The problem has been resolved. Apparently the POP stack had to be reset by the side of the Exchange.

  I hope this helps someone in the future...

• ERROR: Connection failure: unknown username or bad password

  Whenever I want too run a .exe field or a program that requires administrative permissions, I type my password using the account control user, but instead of just let me through it come up with this error:

  Connection failure: unknown username or bad password.

  I searched for fixes, but have not found one that works.

  This was a very big problem I am a player computer and all the games I have, have the administrative sign (shield) and or are .exe files.

  This has happened for about 3 or 4 months now... It really gets me upset. Since there is no way to shut off User Account Control (UAC) without opening UAC itself...

• Recording connection failure attempts

  Someone at - he found a way to get information about connection attempts that have failed where people enter the wrong username/password name? We use the secure gateway and I enabled database. I looked through the database but couldn't find anything by recording connection attempts that failed.

  Hello

  Unfortunately, vWorkspace do not keep track of connection failures, you need a product that collects this information from the event log and stores them for you to review later as Administrator Active or change auditor for Active Directory.

• EqualLogic iSCSI connection limit exceeded - implications?

  We have an EqualLogic SAN iSCSI which exceeded the limits of iSCSI connections. The limit is 1024, but we in 1612. The thing is that nothing seems to be affected. We can still add LUN/servers etc. We are likely to hit the problems? A kind of performance problem? There only seems to be a lot of documentation to anywhere! We are firmware 5.2.2.

  I don't know what we can do to reduce the number of connections, I want to know, is what happens if we don't? Because I can say nothing serious happened. We ignore it? Panic?

  Hello

  Joe is correct, it is very important that you respect the limits of the support of the table.  For you convenience, I suggest you upgrade to EQL FW 6.0.4 and HIT or MEM products for later upgrade.  Firmware 6.x and products current EQL MPIO now work together to better manage connections.  Especially when you are above the limit.  This coordination allows to automatically reduce the number of connections.

  I wonder if you use VMware ESX?   We see quiite often with ESX.  There are a number of strategies to reduce the number of without loss of performance.

  Feel free to open a folder from supported with Dell.   We can examine your environment and make specific recommendations to correct this problem.

  It is very important that you take into account of this.

  Kind regards

• ISE max connection failures

  In ISE, is - anyone know if the tally for the failures of maximum connection for accounts invited (found under settings > comments > political portal page) is one per session or cumulative setting during the lifetime of the account? The County never resets and is there a way to display the current number of connections that have failed?

  Our use case, is that we have guest accounts that distributed to multiple hosts (for example for a hosted conference or special event). We had a couple of this type of accounts get suspended because of hitting max connection failures. We have increased the adjustment, but I would like to understand the parameters more has some of the guest accounts must apply to a significant period of time.

  This is per session, when logged in successfully, the counter is reset.

• Unable to connect to a Samba file server. error "the connection failure: unknown username or bad password?"

  Original title: I can't connect to a server to Samba from Windows 7 files

  I used to use a Mac machine to connect to a file server Samba as smb://myfileserver.mycompany. Now I use a PC with Windows 7 Professional and when I write the address on Explorer as \\myfileserver.mycompany it opens a pop-up to enter my credentials, but when I put my authentication information and click ok, it reminds me the pop-up to try again with a message stating "connection failure: unknown username or bad password.'. '.

  I tried several times but still the same result.

  Is there another way to do this?

  Is there a third party app that will do this job?
